Experimenting with possibilities of a communicative participant research (sounds really scientific, doesn't it?) is in the focus of this contribution. The research partner were people with psychotic experiences, who were till than examination objects in psychological and psychiatric research, and one student of psychology. Starting point for discussing participant research is an accompanying study of the first Berlin "Psychoseseminar" in the district Wedding. The "Weddinger Psychoseseminar" is described as a public forum, in which all participants as experts can learn something from each other. We reconstruct the developing process of the "Weddinger Psychoseseminar". All participants ("Psychoseerfahrene" – psychosis experienced –, relatives, professionals and students) orientate themselves at the normative demands of the "Psychoseseminar" for equal rights and openess. The participants tried to realize these claims. This process is described as not completed. Prerequisites for realizing these claims are demystification of psychosis and that the participants reassure themselves of taking each other seriously. This process was stimulated particularly by the psychosis experienced. They became more and more self-confident and began to point out for instance if participants lost the normative demands of the seminar or the reference to everyday life respectively to practice. Following we discuss the possibilities and limits to communicative participant research, with which we experimented in the context of a working group for the psychosis seminar. Three years after finishing the study, we discuss the effects on the "Psychoseseminar" and primarily on our own development from the view of the ones involved. We – the authors – realize our intension of plural authorship (Clifford, in Berg and Fuchs 1993) at the first time by writing this article.
